1. Deploy the quarkus helm chart on Opensshift

    TypeScript

    To deploy the Quarkus Helm chart on an OpenShift cluster using Pulumi, we should perform the following steps:

    1. Setting up the Pulumi Kubernetes Provider: Before deploying to OpenShift, you need to configure the Pulumi Kubernetes provider to target your OpenShift cluster. This typically involves authenticating against your OpenShift cluster and using the resulting context as your provider instance.

    2. Deploying the Quarkus Helm Chart: Once the provider is set up, you can proceed to deploy the Helm chart. Helm charts are reusable packages of pre-configured Kubernetes resources. In Pulumi, you can deploy Helm charts using the Chart resource from the @pulumi/kubernetes package.

    Below is a Pulumi program written in TypeScript that demonstrates how to deploy a Helm chart to an OpenShift cluster. The program assumes that you have already set up your OpenShift cluster, kubectl, and Pulumi configuration. Please replace <helm-chart-repository> with the actual URL of the Quarkus Helm chart repository, and <chart-version> with the version of the Quarkus chart you wish to deploy.

    import * as k8s from "@pulumi/kubernetes"; // Create a Kubernetes provider instance that targets your OpenShift cluster. const openshiftProvider = new k8s.Provider("openshift", { // Replace these options with the appropriate values for your OpenShift cluster. // This uses the context from your Kubernetes configuration. kubeconfig: "<your-kubeconfig-file>", }); // Deploy the Quarkus Helm chart to your OpenShift cluster. const quarkusChart = new k8s.helm.v3.Chart("quarkus-helm-chart", { // The repository URL where the Quarkus Helm chart is located. repo: "<helm-chart-repository>", chart: "quarkus", // Version of the Helm chart to deploy. version: "<chart-version>", // Values allow you to provide configuration to the chart. values: { // Define any specific values that you need for the Quarkus Helm chart. // Refer to the chart documentation for available options. }, // Ensure this chart is installed in the correct namespace (optional). namespace: "quarkus-namespace", }, { provider: openshiftProvider }); // Make sure to pass in the provider instance. // Export the resulting resource's properties, like its status or endpoint. // In this case, you might want to export the deployed service URL (if applicable). export const quarkusChartStatus = quarkusChart.status; // After running `pulumi up`, you will see any exported values in the output.

    Detailed Explanation:

    • We begin by importing the Pulumi Kubernetes package. This package provides the necessary components to interact with Kubernetes and Helm.

    • We create a Kubernetes provider instance specific to OpenShift by supplying the relevant kubeconfig file that contains our OpenShift cluster configuration.

    • The k8s.helm.v3.Chart resource is then declared to specify the details of the Quarkus Helm chart we wish to deploy. We need to provide at least the name of the chart, where to find its repository, and which version we want to use. values can be modified per your requirements.

    • We also specify the namespace to deploy our Helm chart in; if this namespace does not exist, you should create it beforehand.

    • The provider option allows us to specify that this Helm chart should deploy to the OpenShift cluster we configured above.

    • Finally, we export the status of the Helm chart resource which may include URLs, status conditions, and other important data resulting from the Helm chart deployment.

    Running the program with Pulumi will apply the above declarations to your OpenShift cluster. Ensure that you have Pulumi and kubectl installed and properly configured to communicate with your OpenShift cluster. Save this code to a file, navigate to the directory containing the file via your terminal, and run pulumi up to deploy the Helm chart.
